BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.

This project was created and published by me as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @harisrizwan1/lotide

Require it:

const _ = require('@harisrizwan1/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• assertEqual: Compares the two values it takes in and prints out a message telling us if they match or not.
• head: Returns the first item in an array.
• tail: Returns an array without the first item of the provided array.
• eqArrays: Checks if two arrays are equal.
• AssertArraysEqual: Asserts if two arrays are equal or not
• eqObjects: Checks if two objects are equal.
• assertObjectsEqual: Asserts if two objects are equal or not.
• without: Returns a subset of a given array, removing unwanted elements.
• flatten: Takes in an array containing elements including nested arrays of elements, and returns a "flattened" version of the array.
• middle: Returns the middle-most element(s) of the given array.
• countOnly: Will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• countLetters: Takes in a sentence (as a string) and then returns a count of each of the letters in that sentence.
• letterPositions: Returns all the indices in the string where each character is found.
• findKeyByValue: Takes in an object and a value. Scans the object and returns the first key which contains the given value. If no key with that given value is found, then it returns undefined.
• map: will take in two arguments: An array to map and a callback function. Returns a new array based on the results of the callback function.
• takeUntil: Keeps collecting items from a provided array until the callback provided returns a truthy value.
• findKey: Takes in an object and a callback. It scans the object and returns the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.
